BeV it .known thatyI,AgivroN` I/VELLERT, a citizen; ofbthe United States, residing at Binghamton, in the county of Eroome and State ofi New. Yorlr, have ,invented certain new and useful Improvements in Magnet Fire-Alarm Systems, of Which the .following is specification. 1.* if f .1

My invention relates to .improvements in magnet fire alarm systems and signal systems, and it lhas for its obj ec'txtoprovide a signal mechanism, simple ,in `construction and effective in operatiomyand,controlled and-actuated by the actionof heat, aided by gravity and Whichin practical: operation will produceV signals in",conjunctionr With 0r Without a telephone, vvarningof fire. y

1With these objects in view my invention consists of certain novel features of construction and arrangement of parts, as will be hereinafter more particularly described'and pointed out in the claims, reference being had to the accompanying drawings, in Which- Fig. 1 is a side view of a part of ymy device. Fig. 2 is-a front vievv vof the housing or casing of my device. Y .1

Fig 3 is a side view `of a part ofmy device. Fig. 4 is a side vievv of a partof mydevice. Fig, 5 isI a side elevation of part of my device. 1 Fig. 6 is a front view of my device in casino in operative relation With the tele- D7 phone. Y

The same reference characters denote rlike parts in each ofthe several vfigures ofi the drawings.

In carrying out my invention-and in the construction of my device I providefa casing or housing A vwhich has mounted upon it a hinged lid B, by means ofthe hinges 2, 2;

Within the casing A, I have pivotally mounted an elongated support, on which ismounted a thermometer body C, the support being mounted .on pivot 3; the body C has in its outer end the usual mercury container t, Withtube L1";.the thermometer, body so pivotally supported is kadapted to vbe ytipped into the position shown in the dotted outline C, and to aid in this :pivotal-movement, at the opposite end of Abody C and mounted on 4the support I havethe vertically. projected Weight 4c, and for a graduated-:adjustmentinthe pivotal movement of the body C and balancing of the same, I have mounted in the outer end of the support the turn screvv 5. Mounted on the inner side Wall of the housing A, Ihavea guidefvvay .Y

G having the guides, 74 with inwardly bent edges. Cn the guide Way 6 I slidably mount a. base .plate QhaVingtWo opposite rectan guiar sidesyand `on which vbase platej9, I inouni;tlie"tripping: and; actuating mechanism. D. Mounted also on the inner side Wall ofliousing A, I. have the.- magnet -D. as shown in Fig.-.1. @Overan opening in the lid `Band mounted `in any convenient man-v ner, 4I have the `signal bell 8; the actuating springI gearing and tripping mechanism D of myfdevice is shown .in Figs. 4 and-5, as mounted o n the vplate 9;v the plate 9 has the 2 parallel sides 10, 10. yMounted between thesides. 10, 1() I Vhave a series of shafts; a Windingshaft11, ,on which is mounted the gear 12 and ratchet gear 12 and Winding spring 13; also the shaft 14, on which is mounted gears 15'- and 16, the gear 16 meshing With gear v12; alsofthev shaftl?` on which is mounted the gears 18 4and 18 the `gear 18 meshingy with gear 15; also the shaft17. and on shaft Y17 I have mountedthevratchet 19,l contactingavith gear 18, and also mounted the bell hammer 19 positioned to Contact withv the bell 8 when the lid B isrclosed; also I have theshaft 20and mounted thereon I have the yprojecting tongue 21 positioned to removably contact with hammer 19; on the outer end of shaft 2O I have the turn handle 22, and on the endof shaft 11, I have the Winding handle23; on the side'10 I have mounted :a vertical support, from the ends of Which lproject vthe lugs 24,24 forming a pivotsupport .for the pivot 25 and on 25 I have pivotally mounted the spring bar. 26 having `the outer. vertical end projections 27, 27. Cn the end of plate 9 I have a pivot support 28 and-in which is the pivot 29, and on pivot 29l I have .pivotally mounted the collarl and on which 1 have .mounted the telephonesivitch arm 30 adapted tok vibrate on thepivotalsupport31- vThe arm 30 is formed ofthe body portion a and mounted thereon a curved spring., bar` or trigger support 5,' lthe body a, hasat its inner end the projection 82 and the spring bar bl has at its innen en'd the angular projection 32 adapted to contact with the vertical pin 32 mounted in plate 9 A; :mounted on shaft 11 I vhave a beveled yfaced trip 33the .sloping face of vvhichy is in alinement with theends of projections 82 and 82 and adapted to slidably Contact therewith. On the opposite end of shaft 20, I have the lug 84, adapted When in adjustment` to extend over and contact with .the

pivoted spring bar is tobenotedthat the pivoted support for body C 'is in" alinement with the spring bar 26 and the-vertical end projection 27; and when the mercury.
